DESK.V

SPECIFICATION forming part of Letters Patent No. 269,384, dated December 19, 1882. Application filed March 10,1882. (No model.)

T 0 all whom it may concern:

Be it known that I, WILLIAM M. CAs'rLTo, a citizen ofthe United States, residing at Mechanicsville, in the county of St. Charles and State of Missouri, have invented certain new and useful Improvements in Desks; and I d0 hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperta-ins to make and usethe same, reference being had to the accompanying drawings, and to the letters or ligures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in desks.

It consists substantially in the means I employ whereby asingle motion of a certain part of the desk simultaneously locks the several other parts, as will be hereinafter fully explained, and pointed out in the claims.

In the drawings, Figure l is a vertical section on line w Fig. 3. Fig 2 is a vertical section on line y y, Fig. 3. Fig. 3 is a longitudinal section Ondine z z, Fig. 2, looking from rear of the desk; and in Fig. 4 I show detached views, somewhat enlarged, of parts of my device. Fig. 5 isa perspective ofthe desk with a portion of the front broken away, showing the locking device forthe lid.

A A are the outer and B B the inner vertical sides of my desk.

a b are the drawer-compartments, provider with the proper rails a c to receive the drawers b b', hereinafter described.

c are the side compartments, having the doors c. These doors have on their inner sides the mortise c2. The upper side ot' this mortise' is made large enough to receive the head of the bolt h2 on the locking-bar, hereinafter described, and the sides of the opening of the lower part are contracted, so as to secure the head ot' said bolt in the operation of the locking mechanism, hereinafter described.

d is the top of the desk, to which I hinge the lifting lid d'. To the under side of the forward portion of this lid I tix the staple d2, arrangedl in position to enter the mortise d3 when the lid is shut down.

b b' are the drawers, sliding on the rails c a in compartments a b, as shown. These tion when turned down,

drawers are constructed with the slots b2 in the upper part of their sides, next the vertical sides B ot' the desk, and these slots are arranged in proper position to be entered by the pins or locking-bar, hereinafter described.

c is the upper or pigeon-hole compartment ofthe desk, extending the whole width ot' the same.

-\ e is the door, hinged at the bottom.

e2 e2 are triggers pivoted-to the inner side of the door e', and arranged in proper posias shown in full lines, Figs. 1, 2, and 3, to press on the top ot' the lock-bar, hereinatter described, and bear the same down and lock the several. parts of the desk when the door e is shut, as will be described. When the triggers are turned up, as shown in dotted lines, Fig. 3, the opening and closing ofthe door e will not aii'ect the locking-bar.

fis a bar or rod pivoted at x, Fig. 4, within the forward part ofthe desk, under the lid d. It is provided at one end with the hook j", ex tended to and working in the mortise d3, here inbetore described, and its opposite end,f2, is bent and connected to the burg, as will bedescribed.

g is a bar arranged next the side B in upper part ot compartment a. This bar is pressed .rearward by a spring, g', arranged and bearing between the forward part ot' the said b ar g and inner side of the front of the desk./ The rear end ot' the bar g is beveled, and is engaged by the beveled side ot' thewprojection on the main locking-bar, as will be described. Near the forward part of the bar y, Icut a mortise, g2, in which the end f2 of the rodfpresses, whereby the said rod fand bar g are connected.

h 7i are the lock-bars. They are arranged within the compartments c a and c b, next the sides B, and extend from near the bottom ot' the desk to within the pigeon-hole compartment e. These rods stand on the springs h', which support them up to the position shown in Figs. l and 3 when they4 are not pressed down by the triggers e2, as will be described.

h2 h2 are bolts formed with suitable heads, h3 h3, adapted to enter the mortises u2 in doors c and lock the said doors, as will be described.

IOO

It* are pins fixed to the side of the bar h, and arranged in proper position to enter the slots b2 in sides of drawers b' and lock the drawers when the bar h is pressed down, as will be described.

h5 is a projection on forward part of the bar h, next the beveled end of bar g, and the forward part ot this projection is beveled correspondingly to and bears against the beveled end ofthe bar g, andis constructed, as will be seen, to operate, when the bar his pressed down, to force the. bar g forward, which carries with it the end being pivoted, this motion carries the hook f forward into the mortise d3, and into the staple d2 on the lid d. when the said lid is shutdown.

In the operation of my device, when the several parts are in the position shown in Fig. l and it is desired to lock them I close the door c. This carries the triggers e against the top of bar h, forcing downward the said bar with its bolts h2, pins h4, and the beveled projection h5, the said projection pressing the bar g forward. Thus the head h3 of bolt h2, being within the upper end of mortise c2, is pressed down between the contracted sides ot' lower part of said mortise and secures the doors c. The pins 7c.u1 press down inthe slots b2 in top of drawers and lock the same, and the bar g, being pressed forward by the projection lr", carries the end f2 of the rodf, which forces the hook f into the staple d2 on lid d', and the said lid is securely locked.

It will be seen that by turning one of the triggers up, as shown in dotted lilies, Fig. 3, the drawers ou one side of the desk can be locked and the others remain unlocked, and by connecting the staple d2 so that it may be turned up against the under side ot' the lid I can lock the lid or not, as desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

l. The combination, with the desk having drawers b', and the upper compartment, e, and the door 6', hinged to close the compartment c,

f2 of the rod j', and the said rod f of the bar h, provided with pins arranged to engage and lock the drawers b', and having its upper end projected into the compartment e, and the triggers e2, placed on the inner side ot' the door e and adjustable to engage or clear the projected upper end ot' bar h, substantially as set forth.

2. The combination, substantially as hereinbefore set forth, of the drawers b', constructed with slots b2, bars h, provided with pins h4 and bolts h2, constructed with heads h3, doors c', having the mortises c2 on their inner sides, the lower sides ofthe opening of said mortises being contracted to secure the head h3 on bolt h", door e', and trigger e?, as and for the purposes set forth.

3. 'Ihe combination, substantially as hereinbefore set forth,ot` the'lid d', provided with staple dz, rodf, having hookf working in mortise d3 and connected to bar g, bar g, supported by spring g' and having its rear side beveled, bar h, supported on spring h' and provided with projection h5, arranged to bear on the beveled end of rod g, and means for depressing the bar h, as and for the purposes described.

4. rIhe combination of the drawers b', having slots b", bars h, having bolts h2 and pins h4 and beveled projection h5, doors c, having mortises c2, doors e', having triggers e2, bar g,

connected to rodf, rod f, pivoted and provided with hook f', and lid d', provided with staple cl2, substantiallyas and for' the purposes set forth.

5. The combination, substantially as described, of the doors c', constructed with mortises c2, having the lower sides of their opening contracted, as shown, the bar-lt, provided with pin h2, having head h3, and means for operating the bar h, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
